The Sage Arrow is a 9'0" fly rod series that stays squarely in the all-around category, with different weights aimed at very different jobs. The 4WT is the most finesse-leaning option Sage lists, focused on dry flies and smaller nymphs with an emphasis on line control and accuracy. The 5WT is the broadest trout tool in the group, meant to cover a wide range of trout flies and to handle lines with different sink rates. Moving to 6WT shifts the Arrow toward bigger water and more wind tolerance, with Sage calling out big river trout, smallmouth, and larger flies. The 6WT FB pushes farther into big flies and gusty conditions. The 8WT is the jump to salmon, stripers, and largemouth bass.
